Geologicheskii Vestnik

The article is the first to publish materials on the conodont characteristics of the ore-bearing volcanogenic-sedimentary formations in the Magnitogorsk ore field. They were obtained during the of geological mapping in the late 80s. On the basis of the conodonts study, a detailed stratigraphic subdivision of the Upper Devonian and Lower Carboniferous formations lacking faunal characteristic, was made. In the composite section of the Shumilin Formation, an almost complete sequence of the Famennian Horizons of the Upper Devonian and the Tournaisian of the Lower Carboniferous stages were determined. In the Famennian the Makarovsky, Murzakaevsky, Kushelginsky and Lytvinsky Horizons of the West Urals stratigraphic scheme are distinguished. In the Tournaisian the Gumerovsky, Malevsky, Upinsky, Kosorechensky, Kizelovsky and Kos’vinsky Horizons are established.
